A
To represent radioactive decay
2
Q
How is an alpha particle represented
A
By the alpha symbol with mass number 4 and atomic number 2
3
Q
How is a beta particle represented
A
By the beta symbol with mass number 0 and atomic number minus 1
4
Q
What effect does alpha decay have on a nucleus
A
It decreases both mass and charge
5
Q
What effect does beta decay have on a nucleus
A
It increases nuclear charge but mass stays the same
6
Q
What should students be able to do with nuclear equations
A
Balance atomic and mass numbers for alpha and beta decay
7
Q
Does gamma emission change the mass or charge of a nucleus
A
No it causes no change in mass or charge
